Double Reflective Stitching: Reflective yarn is woven into the webbing and non-shift pad for night-time visibility. Comfortable: Padded for extra comfort & support. Control Harness transfers pressure from your dog’s neck to its chest. The Rogz Stop-Pull Harness can be used with a regular lead or a double ended lead depending on the level of control required.
